Patented Mar. 3, 1931 UNITED STATES PATENT OFFICE NILS A. WAHLBERG, OFWILKINSBURG, PENNSYLVANIA, ASSIGNOR TO WESTINGHOUSE ELECTRIC &MANUFACTURING COMPANY, A CORPORATION OF PENNSYLVANIA INSULATOR OONNECTERApplication. filed February 19, 1921.

My invention relates to connecters and particularly to connecters forstrain insulators.

The object of my invention is to provide a strain-insulator connecterthat shall be simple in construction and manipulation, economical tomanufacture and reliable and effective in operation and that shall besymmetrical and pleasing in appearance.

Heretofore, certain connecters for strain insulators of theporcelain-block or petticoat types, having right-angularly related seatsor openings and interlinked metal members disposed in the openings, havebeen comparatively complicated and expensive in construction, of largesize and uns mmetrical in form and have had other un esirablecharacteristics, as in those embodying stranded metal cables. The latterusually require splicing or other construction of complicated andexpensive character.

In practicing my invention, I provide a connecter, for disposition atone end of an insulator, comprising a member constructed of a section ofstandard rod or wire and formed to substantially C-shape by a simple Thefree ends of the member are bent inwardly for insertion through openingsin a second member and are threaded to receive holding nuts. The secondmember is constructed of standard strap or sheet metal bent tosubstantially loop shape, with the above mentioned openings at anintermediate portion thereof. Apertured projections at the free ends ofthe second looped member are adapted to attach the insulator to asupporting device or to an adjacent similar insulator.

The single figure of the accompanying drawing is a side elevational viewof a strain insulator on which connecters embodying my invention aremounted.

A block 1 of insulating material, preferably of porcelain, is providedwith rightangularly related openings 2 and 3, of laterally-curvedcontour, for the reception of interlinked metal members 4.- and 5,respectively. The latter, preferably constructed of standard rod or wirematerial, are shaped and mounted in position in the block 1 by SerialNo. 446,401.

bending and have inwardly-bent, threaded outer ends 6 and 7.

End or terminal members 8 and 9, preferably constructed of standard fiatstrap or sheet metal, are bent to substantially pentagonal shape havingspaced apertured projections 10 extending outwardly from the ends or"adjacent or intersecting sides 11 and 12 of the pentagonal portionthereof.

Sides 13 and 14 of the members 8 and 9 are provided with openings 15 forthe reception of the ends 6 and 7 of the members 4 and 5. Nuts 16 areprovided on the ends 6 and 7 to hold the members 4 and 8 and the members5 and 9 together.

In assembling the device, the ends 6 and 7 are first bent to shape andthe members 4 and 5 placed in the openings 2 and 3 while the ends 6 and7 are spaced apart a distance suificient to permit their ready placingin the openings. with the members 8 and 9 in the positions shown, theends 6 and 7 are then bent to final position and the nuts 16 mountedduring this bending operation.

By having the ends 6 and 7 inwardly bent towards each other, theterminal members 8 and 9 are rendered smaller and more compact and aremore readily constructed of standard sheet or strap material. The deviceis thereby, rendered more economical and of less weight than it would beif the ends 6 and 7 were merely straight continuations of the legs ofthe members 1 and 5, respectively.

The structure constitutes a simple and etfective, unitary,readily-transportable device that is economical to manufacture. Further,it is of symmetrical form and pleasing appearance, has relatively shortoverall length and may be quickly installed by the simple expedient ofplacing bolts through the openings 15.

While I have shown anddescribed a particular form of my invention,changes may be effected therein without departing from the spirit andscope thereof, as set forth in the appended claims. 1

I claim as my invention:

1. A tension connecter comprising an ele ment of substantially U-shapehaving its free ends inclined toward each other, a member having anintermediate portion of substantially C-shape and end portionsprojecting outwardly therefrom, said intermediate portion having a pairof openings through Which it receives said inclined ends, andenlargements on said inclined ends insidesaid intermediate portion.

2. A tension conneeter comprising an element of substantially U-shapehaving the free ends of its side arms inclined toward each other, amember having an intermediate portion of substantially C-shape disposed,With its closed rear side adjacent to said free ends and having its armsextending away "from the member of U-shape 1n the general direction ofsaid first arms and means for holding said inclined ends in operativerelation to said closed rear side. 7

In testimony whereof, I have hereunto subscribed my name this 11th dayof February,

mm A. WAHLBERG.
